IMPROVED MOSQUITO TENT OR FRAME.

Specification forming part of Letters Patent No. 41,946, dated March 15,1864; antcdated March 5, 1864.

To all whom it may concern:

Be it known that I, JOHN STEWART, of the city, county, and State of NewYork, have invented a new and Improved Mosquito-House; and I do herebydeclare that the following is afull, clear, and exact description ofthesame, reference bei nghad to the accompanying drawings, forming a partof this specification, in which- I Figure l represents a verticalcentral section of my invention. Fig. 2 is a plan or top View of thesame.

Similar letters of reference in both views indicate corresponding parts.

The object of this inventionis a simple and portable device capable ofbeing raised and expanded to forma space inclosed by mos` quito-netting,or of being lowered and folded up so as to occupy but little room whenit is not used.

The invention consists in the arrangement of a standard or columncomposed of two or more tubes sliding one within the other in the mannerof a telescope, said column being provided with a windlass and suitablehoisting ropes or chains, and with folding arms in such a manner that bythe act of extending the column the folding arms are expanded or raisedto a horizontal position, and a 'mosquitonetting of a suitable shapethrown over said arms will afford protection to several persons againstthe attacks of mosquitos either in a room or out offdoors.

To enable those skilled in the art to'make and use my invention, I willproceed to describe it. y

A represents a column or standard, which is firmly secured to a bedplate or foot, B, in an upright position, as clearly shown in Fig. 1 ofthe drawings. The column A is hollow and made of two or more sections, al, the section b being made to slide in the section a i'n the manner ofa telescope.

C is a windlass, which is operated by a handwheel, c, its bearingsbeing' near the bottom From this windlass two ropes, d c, extend overpulleys d e', rotating on a rod, f, which is firmly fastened in theupper part ofthe tube a, and thence down to the lower end of the innertube, b, this tube being provided with slots g, to allow it to slide upand down on the rod f. By turning the windlass in the proper directionthe ropes d e wind up on it and the inner tube is elevated until theinner ends of the arms strike the surface of the inner tube and preventa further upward motion of the same. A dog or catch, f', retains thewindlass in any position.

D are arms, which are hinged to the upper part of the tube b, so thatthe same, when allowed to follow their inherent gravity, hang down onthe outside ofthe column A. Each arm is provided with a hook, h, and arope, fi, extends from this hook over a pulley, j, rotating on a pivotin the upper end of the tube b. The several ropes z extend down to therod f, andare fastened to the saine by knots or in any other suitablemanner. If the tube b is down, the ropes are slack, and the arms D hangdown, but as soon as the tube b begins to rise, a strain is exerted onthe ropes fi, and the arms begin to rise, and when the tube has reachedits highest position the arms D extend in ahorizontal direction from thesanne, as clearly shown in the drawings. Each of the arms D is made oftwo sections, which are connected by set-screws k, fastened to oneseotion and sliding in slots Z in the other section, so that said armscan be lengthened or shortened at pleasure. If desired, the outersections .of the arms may be connected to the ropes t' in such a mannerthat the arms are extended as the tube b rises. In most cases, however,it will he more convenient to extend the arms by means of the set-screwsand slots, whereby their length can be readily accommodated to suit theoccasion. The outer ends of the arms D are provided with curved anges m,to prevent injury to the mosquito-netting, which is fastened to theupper end of the column A and hung over the arms, as indicated in redoutlines in Fig. 1. The netting ought to be cut out and made in such ashape that the same hangs down ou the floor or ground and incloses aspace sufficiently large to give several persons a shelter against theattack of mosquitoes.

lIhis device can be used in a room or out doors with equal advantage,and when not used it can loe readily lowered and put away in a smallcompass.

Vhat I claim as new, and desire to secure by Letters Patent, is-

The telescope-column A, provided with a windlass, C, ropes or chains clve, hinged arms D, and ropes or chains z', all constructed and operatingin the manner and for the purpose herein shown and described.

Vitnesses: JOHN STEWART.
